Notwithstanding the foregoing, any such Holder that surrenders for conversion any Security (a) that has been called for redemption by the Company in a notice of redemption given by the Company pursuant to Section 10.04 hereof on a Redemption Date after such Regular Record Date and on or prior to the next succeeding Interest Payment Date, (b) with respect to which the Company has specified a Purchase Date that is after such Regular Record Date and on or prior to the next succeeding Interest Payment Date or (c) on which Defaulted Interest is payable at the time of conversion, but only to the extent of such Defaulted Interest. In either case described in clause (a) or clause (b) above, such Holder shall be entitled to receive (and retain) such

9

interest and need not pay the Company an amount equal to the interest on the principal amount of such Security so converted at the time such Holder surrenders such Security for conversion.

        Principal of and interest on, Global Securities shall be payable to the Depositary in immediately available funds.

        Principal on Physical Securities shall be payable at the office or agency of the Company maintained for such purpose, initially the Corporate Trust Office of the Trustee. Interest on Physical Securities will be payable by (i) U.S. Dollar check drawn on a bank located in the city where the Corporate Trust Office of the Trustee is located mailed to the address of the Person entitled thereto as such address shall appear in the Register, or (ii) upon application to the Registrar not later than the relevant Record Date by a Holder of an aggregate principal amount in excess of $5,000,000, wire transfer in immediately available funds.

        The Securities shall be redeemable at the option of the Company as provided in Article 10 hereof.

        The Securities shall have the Purchase Rights exercisable at the option of Holders as provided in Article 11 hereof.

        The Securities shall be convertible as provided in Article 12 hereof.

        Section 2.02.    Form of Securities.     The Securities and the Trustee's certificate of authentication to be borne by such Securities shall be substantially in the form annexed hereto as Exhibit A, which is incorporated in and made a part of this Indenture. The terms and provisions contained in the form of Security shall constitute, and are hereby expressly made, a part of this Indenture and to the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.

        Any of the Securities may have such letters, numbers or other marks of identification and such notations, legends and endorsements as the Officer executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Securities may be listed or designated for issuance, or to conform to usage.

        The Securities will be offered and sold only to QIBs in reliance on Rule 144A and shall be issued initially only in the form of one or more permanent Global Securities (each, a "Global Security") in registered form without interest coupons. The Global Securities shall be:

        (1)   duly executed by the Company and authenticated by the Trustee as hereinafter provided;

        (2)   registered in the name of the Depositary (or its nominee) for credit to the respective accounts of the Holders at the Depositary; and

        (3)   deposited with the Trustee, as custodian for the Depositary.

        The Global Securities shall be substantially in the form of Security set forth in Exhibit A annexed hereto (including the text and schedule called for by footnotes 1 and 2 thereto). The aggregate principal amount of the Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee as required by Section 2.09, as custodian for the Depositary (or its nominee), in accordance with the instructions given by the Holder thereof, as hereinafter provided.

        Securities issued in exchange for interests in the Global Securities pursuant to Section 2.08(d) hereof shall be issued in the form of permanent definitive Securities (the "Physical Securities") in registered form without interest coupons. The Physical Securities shall be substantially in the form set forth in Exhibit A annexed hereto.

10

        The Securities shall be typed, printed, lithographed or engraved or produced by any combination of these methods or may be produced in any other manner permitted by the rules of any securities exchange on which the Securities may be listed, all as determined by the Officer executing such Securities, as evidenced by their execution of such Securities.

        Section 2.03.    Legends.     (a) Restricted Securities Legends.    Each Security issued hereunder shall, upon issuance, bear the legend set forth in Section 2.03(a)(i) or Section 2.03(a)(ii) (each, a "Restricted Securities Legend"), as the case may be, and such legend shall not be removed except as provided in Section 2.03(a)(iii). Each Security that bears or is required to bear the Restricted Securities Legend set forth in Section 2.03(a)(i) (together with any Common Stock issued upon conversion of the Securities and required to bear the Restricted Securities Legend set forth in Section 2.03(a)(ii), collectively, the "Restricted Securities") shall be subject to the restrictions on transfer set forth in this Section 2.03(a) (including the Restricted Securities Legend set forth below), and the Holder of each such Restricted Security, by such Holder's acceptance thereof, shall be deemed to have agreed to be bound by all such restrictions on transfer.

        As used in Section 2.03(a), the term "transfer" encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

        (i)    Restricted Securities Legend for Securities.    Except as provided in Section 2.03(a)(iii), until the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), any certificate evidencing such Security (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear the legend set forth in Section 2.03(a)(ii), if applicable) shall bear a Restricted Securities Legend in substantially the following form:

THIS DEBENTURE (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933 ("THE "SECURITIES ACT"), AND THIS DEBENTURE AND THE COMMON STOCK ISSUABLE UPON CONVERSION THEREOF MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS DEBENTURE IS HEREBY NOTIFIED THAT THE SELLER OF THIS DEBENTURE MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.

THE HOLDER OF THIS DEBENTURE AGREES FOR THE BENEFIT OF NOVELL, INC. (THE "COMPANY") THAT (A) THIS DEBENTURE AND THE COMMON STOCK ISSUABLE UPON CONVERSION THEREOF MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE), (III) TO THE COMPANY OR ANY SUBSIDIARY THEREOF OR (IV) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (IV) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS DEBENTURE FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE.

11

        (ii)    Restricted Securities Legend for Common Stock Issued upon Conversion of the Securities.    Except as provided in Section 2.03(a)(iii), until the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), any stock certificate representing Common Stock issued upon conversion of such Security shall bear a Restricted Securities Legend in substantially the following form:

THE COMMON STOCK EVIDENCED HEREBY (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933 ("THE "SECURITIES ACT"). THE HOLDER OF THIS CERTIFICATE AGREES FOR THE BENEFIT OF NOVELL, INC. (THE "COMPANY") THAT (A) THIS DEBENTURE AND THE COMMON STOCK ISSUABLE UPON CONVERSION THEREOF MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE), (III) TO THE COMPANY OR ANY SUBSIDIARY THEREOF OR (IV) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (IV) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS DEBENTURE FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE.

        (iii)    Removal of the Restricted Securities Legends.    Each Security or share of Common Stock issued upon conversion of such Security shall bear the Restricted Securities Legend set forth in Section 2.03(a)(i) or 2.03(a)(ii), as the case may be, until the earlier of:

        (A)  the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision);

        (B)  such Security or Common Stock has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and that was effective at the time of such sale); or

        (C)  such Common Stock has been issued upon conversion of Securities that have been sold pursuant to a registration statement that has been declared effective under the Securities Act (and that was effective at the time of such sale).

        The Holder must give notice thereof to the Trustee and any transfer agent for the Common Stock, as applicable.

        Notwithstanding the foregoing, the Restricted Securities Legend may be removed if there is delivered to the Company such satisfactory evidence, which may include an opinion of independent counsel, as may be reasonably required by the Company, that neither such legend nor the restrictions on transfer set forth therein are required to ensure that transfers of such Security will not violate the registration requirements of the Securities Act. Upon provision of such satisfactory evidence, the Trustee, at the written direction of the Company, shall authenticate and deliver in exchange for such Securities another Security or Securities having an equal aggregate principal amount that does not bear such legend. If the Restricted Securities Legend has been removed from a Security as provided above, no other Security issued in exchange for all or any part of such Security shall bear such legend, unless the Company has reasonable cause to believe that such other Security is a "restricted security" within

12

the meaning of Rule 144 and instructs the Trustee in writing to cause a Restricted Securities Legend to appear thereon.

        Any Security (or security issued in exchange or substitution thereof) as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the Restricted Securities Legend set forth in Section 2.03(a)(i) as set forth therein have been satisfied may, upon surrender of such Security for exchange to the Registrar in accordance with the provisions of Section 2.07 hereof, be exchanged for a new Security or Securities, of like tenor and aggregate principal amount, which shall not bear the Restricted Securities Legend required by Section 2.03(a)(i).

        Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the Restricted Securities Legend set forth in Section 2.03(a)(ii) as set forth therein have been satisfied may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the Restricted Securities Legend required by Section 2.03(a)(ii).

        (b)    Global Security Legend.    Each Global Security shall also bear the following legend on the face thereof:

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY ("DTC") TO NOVELL, INC. (OR ITS SUCCESSOR) OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE, CONVERSION OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

        Section 2.04.    Execution, Authentication, Delivery and Dating.     An Officer shall execute the Securities on behalf of the Company by manual or facsimile signature. If the Officer whose signature is on a Security no longer holds that office at the time the Security is authenticated, the Security shall be valid nevertheless.

        At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise.

        Each Security shall be dated the date of its authentication.

        No Security shall be entitled to any benefit under this Indenture, or be valid or obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by or on behalf of the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

        The Trustee may appoint an authenticating agent or agents reasonably acceptable to the Company with respect to the Securities. Unless limited by the terms of such appointment, an authenticating agent

13

may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.

        Section 2.05.    Registrar and Paying Agent.     The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the "Registrar") and an office or agency where Securities may be presented for payment (the "Paying Agent"). The Registrar shall keep a register of the Securities (the "Register") and of their transfer and exchange. The Company may appoint one or more co-Registrars and one or more additional Paying Agents for the Securities. The term "Paying Agent" includes any additional paying agent and the term "Registrar" includes any additional registrar. The Company may change any Paying Agent or Registrar without prior notice to any Holder.

        The Company will cause each Paying Agent (other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will:

          (i)  hold all sums held by it for the payment of the principal of or interest (including Liquidated Damages, if any) on Securities in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as provided in this Indenture;

         (ii)  give the Trustee notice of any Default by the Company in the making of any payment of principal or interest (including Liquidated Damages, if any); and

        (iii)  at any time during the continuance of any such Default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

        The Company shall give prompt written notice to the Trustee of the name and address of any Paying Agent who is not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent or Registrar; provided, however, that none of the Company, its Subsidiaries or the Affiliates of the foregoing shall act:

          (i)  as Paying Agent in connection with redemptions, offers to purchase and discharges, as otherwise specified in this Indenture, and

         (ii)  as Paying Agent or Registrar if a Default or Event of Default has occurred and is continuing.

        The Company hereby initially appoints the Trustee as Registrar and Paying Agent for the Securities.

        Section 2.06.    Paying Agent to Hold Assets in Trust.     Not later than 12:00 Noon (New York City time) on each due date of the principal and interest (including Liquidated Damages, if any) on any Securities, the Company shall deposit with one or more Paying Agents money in immediately available funds sufficient to pay such principal and interest (including Liquidated Damages, if any) so becoming due. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company) shall have no further liability for the money so paid over to the Trustee.

        If the Company shall act as a Paying Agent, it shall, prior to or on each due date of the principal of or interest (including Liquidated Damages, if any) on any of the Securities, segregate and hold in trust for the benefit of the Holders a sum sufficient with monies held by all other Paying Agents, to pay the principal or interest (including Liquidated Damages, if any) so becoming due until such sums shall be paid to such Persons or otherwise disposed of as provided in this Indenture, and shall promptly notify the Trustee of its action or failure to act.

14

        Section 2.07.    General Provisions Relating to Transfer and Exchange.     The Securities are issuable only in registered form. A Holder may transfer a Security only by written application to the Registrar stating the name of the proposed transferee and otherwise complying with the terms of this Indenture. No such transfer shall be effected until, and such transferee shall succeed to the rights of a Holder only upon, final acceptance and registration of the transfer by the Registrar in the Register. Furthermore, any Holder of a Global Security shall, by acceptance of such Global Security, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by the Holder of such Global Security (or its agent) and that ownership of a beneficial interest in the Security shall be required to be reflected in a book-entry. Notwithstanding the foregoing, in the case of a Restricted Security, a beneficial interest in a Global Security being transferred in reliance on an exemption from the registration requirements of the Securities Act other than in accordance with Rule 144 and Rule 144A may only be transferred for a Physical Security.

        When Securities are presented to the Registrar with a request to register the transfer or to exchange them for an equal aggregate principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met (including that such Securities are duly endorsed or accompanied by a written instrument of transfer duly executed by the Holder thereof or by an attorney who is authorized in writing to act on behalf of the Holder). Subject to Section 2.04 hereof, to permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar's request. No service charge shall be made for any registration of transfer or exchange or redemption of the Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or other similar governmental charge payable upon exchanges pursuant to Section 2.14, 7.05 or 10.07 hereof).

        In the event of a redemption in part, neither the Company nor the Registrar shall be required to issue, register the transfer of, or exchange, Securities during the period of 15 days before the mailing of the notice of redemption.

        Section 2.08.    Book-Entry Provisions for the Global Securities.     (a) The Global Securities initially shall

          (i)  be registered in the name of the Depositary (or a nominee thereof);

         (ii)  be delivered to the Trustee as custodian for such Depositary; and

        (iii)  bear the Restricted Securities Legend as set forth in Section 2.03(a)(i) hereof.

        Members of, or participants in, the Depositary ("DTC Participants") shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under such Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing contained herein shall prevent the Company, the Trustee or any agent of the Company or Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and the DTC Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

        (b)   The registered Holder of a Global Security may grant proxies and otherwise authorize any Person, including DTC Participants and Persons that may hold interests through DTC Participants, to take any action that a Holder is entitled to take under this Indenture or the Securities.

        (c)   A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary (or a nominee thereof), and no such transfer to any such other Person may be registered.

15

Beneficial interests in a Global Security may be transferred in accordance with the rules and procedures of the Depositary and the provisions of Section 2.09 hereof.

        (d)   Notwithstanding any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered in the name of any person other than the Depositary or one or more nominees thereof, provided that a Global Security may be exchanged for Securities registered in the names of any person designated by the Depositary in the event that (i) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or such Depositary has ceased to be a "clearing agency" registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days, (ii) to the extent permitted by the Depositary, the Company determines at any time that the Securities shall no longer be represented by Global Securities and shall inform such Depositary of such determination and participants in such Depository elect to withdraw their beneficial interests in the Global Securities from such Depository, following notification by the Depository of their right to do so; or (iii) a beneficial owner of Securities requests to exchange such beneficial owner's interest in the Global Securities for Certificated Securities. Any Global Security exchanged pursuant to clause (i) above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (ii) or (iii) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided that any such Security so issued that is registered in the name of a person other than the Depositary or a nominee thereof shall not be a Global Security.

        Upon the occurrence of (i), (ii) or (iii) above, the Depositary shall surrender such Global Security or Global Securities to the Trustee for cancellation and the Company shall execute, and the Trustee, upon receipt of an Officers' Certificate and Company Order for the authentication and delivery of Securities, shall authenticate and deliver in exchange for such Global Security or Global Securities, Physical Securities of like tenor as that of the Global Securities in an aggregate principal amount equal to the aggregate principal amount of such Global Security or Global Securities. Such Physical Securities shall be registered in such names as the Depositary shall identify in writing as the beneficial owners of the Securities represented by such Global Security or Global Securities (or any nominees thereof).

        Notwithstanding the foregoing, in connection with any such surrender and subsequent exchange pursuant to Section 2.08(d) hereof, the Registrar shall reflect on its books and records the date and a decrease in the principal amount of such Global Security in an amount equal to the principal amount of the beneficial interest in such Global Security to be transferred.

        Section 2.09.    Special Transfer Provisions.     Unless a Security is transferred after the time period referred to in Rule 144(k) under the Securities Act or otherwise sold pursuant to a registration statement that has been declared effective under the Securities Act (and that continues to be effective at the time of such sale), the following provisions shall apply:

          (i)  if the Securities to be transferred consist of an interest in the Global Securities, the transfer of such interest may be effected only through the book-entry system maintained by the Depositary; and

         (ii)  if the Securities to be transferred consist of Physical Securities, the Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided on the form of Security stating, or has otherwise advised the Company and the Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a

16

transferee who has signed the certification provided on the form of Security stating or has otherwise advised the Company and the Registrar in writing that:

        (A)  it is purchasing the Securities for its own account or an account with respect to which it exercises sole investment discretion, in each case for investment and not with a view to distribution;

        (B)  it and any such account is a QIB within the meaning of Rule l44A;

        (C)  it is aware that the sale to it is being made in reliance on Rule 144A;

        (D)  it acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information; and

        (E)  it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A.

        By its acceptance of any Security bearing the Restricted Securities Legend, each Holder of such a Security acknowledges the restrictions on transfer of such Security set forth in this Indenture and agrees that it will transfer such Security only as provided in this Indenture. The Registrar shall not register a transfer of any Security unless such transfer complies with the restrictions on transfer of such Security set forth in this Indenture. The Registrar shall be entitled to receive and rely on written instructions from the Company verifying that such transfer complies with such restrictions on transfer. In connection with any transfer of Securities, each Holder agrees by its acceptance of the Securities to furnish the Registrar or the Company such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act; provided, however, that the Registrar shall not be required to determine (but may rely on a determination made by the Company with respect to) the sufficiency of any such certifications, legal opinions or other information.

        The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.08 hereof or this Section 2.09. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

        Section 2.10.    Holder Lists.     The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders and shall otherwise comply with Section 312(a) of the TIA. If the Trustee is not the Registrar, the Company shall furnish to the Trustee prior to or on each Interest Payment Date and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders relating to such Interest Payment Date or request, as the case may be.

        Section 2.11.    Persons Deemed Owners.     The Company, the Trustee and any agent of the Company or the Trustee may treat the registered Holder of a Global Security as the absolute owner of such Global Security for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether or not such Security be overdue, and notwithstanding any notice of ownership or writing thereon, or any notice of previous loss or theft or other interest therein. The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Security is registered as the owner of such Security for the purpose of receiving payment of principal of and interest (including Liquidated Damages, if any) on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and notwithstanding any notice of ownership or writing thereon, or any notice of previous loss or theft or other interest therein.

17

        Section 2.12.    Mutilated, Destroyed, Lost or Stolen Securities.     If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding.

        If there is delivered to the Company and the Trustee

          (i)  evidence to their satisfaction of the destruction, loss or theft of any Security, and

         (ii)  such security or indemnity as may be required by them to save each of them and any agent of either of them harmless,

then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and, upon request, the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding.

        In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion, but subject to any conversion rights, may, instead of issuing a new Security, pay such Security, upon satisfaction of the condition set forth in the preceding paragraph.

        Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

        Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and such new Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

        The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

        Section 2.13.    Treasury Securities.     In determining whether the Holders of the requisite principal amount of Outstanding Securities are present at a meeting of Holders for quorum purposes or have given any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned by the Company or any Affiliate of the Company shall be disregarded and deemed not to be Outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such determination as to the presence of a quorum or upon any such request, demand, authorization, direction, notice, consent or waiver, only such Securities of which the Trustee has received written notice and are so owned shall be so disregarded.

        Section 2.14.    Temporary Securities.     Pending the preparation of Securities in definitive form, the Company may execute and the Trustee shall, upon written request of the Company, authenticate and deliver temporary Securities (printed or lithographed). Temporary Securities shall be issuable in any authorized denomination, and substantially in the form of the Securities in definitive form but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every such temporary Security shall be executed by the Company and authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the Securities in definitive form. Without unreasonable delay, the Company will execute and deliver to the Trustee Securities in definitive form (other than in the case of Securities in global form) and thereupon any or all temporary Securities (other than any such Securities in global form) may be surrendered in exchange therefor, at each office or agency maintained by the Company

18

pursuant to Section 9.02 and the Trustee shall authenticate and deliver in exchange for such temporary Securities an equal aggregate principal amount of Securities in definitive form. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Securities in definitive form authenticated and delivered hereunder.

        Section 2.15.    Cancellation.     All securities surrendered for payment, redemption, purchase, conversion, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities so delivered shall be canceled promptly by the Trustee, and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. Upon written instructions of the Company, the Trustee shall destroy canceled Securities and, after such destruction, shall deliver a certificate of such destruction to the Company. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless the same are delivered to the Trustee for cancellation.

        Section 2.16.    CUSIP Numbers.     The Company in issuing the Securities may use "CUSIP" numbers (if then generally in use), and the Trustee shall use CUSIP numbers in notices of redemption or exchange as a convenience to Holders; provided, however, that any such notice shall state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any such notice and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any change in the CUSIP numbers.

        Section 2.17.    Defaulted Interest.     If the Company fails to make a payment of interest (including Liquidated Damages, if any) on any Security when due and payable ("Defaulted Interest"), it shall pay such Defaulted Interest plus (to the extent lawful) any interest payable on the Defaulted Interest, in any lawful manner. It may elect to pay such Defaulted Interest, plus any such interest payable on it, to the Persons who are Holders of such Securities on which the interest is due on a subsequent Special Record Date. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Security. The Company shall fix any such Special Record Date and payment date for such payment. At least 15 days before any such Special Record Date, the Company shall mail to Holders affected thereby a notice that states the Special Record Date, the Interest Payment Date, and amount of such interest (and such Liquidated Damages, if any) to be paid.

        Section 2.18.    Rule 144A.     The Company agrees that it will refuse to register any transfer of Securities or Common Stock that is not made in accordance with the provisions of Rule 144A under the Securities Act, pursuant to a registration statement that has been declared effective under the Securities Act or pursuant to an available exemption from the registration requirements of the Securities Act; provided that this Section 2.18 shall not be applicable to any Securities or shares of Common Stock that do not bear the legend set forth in Section 2.03(a)(i) or (ii) hereof.

        Section 4.02.    Acceleration of Maturity; Rescission and Annulment.     If an Event of Default with respect to Outstanding Securities (other than an Event of Default specified in Section 4.01(g) or 4.01(h) hereof) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Outstanding Securities, by written notice to the Company, may declare due and payable 100% of the principal amount of all Outstanding Securities plus any accrued and unpaid interest (including Liquidated Damages, if any) to the date of payment. Upon a declaration of acceleration, such principal and accrued and unpaid interest (including Liquidated Damages, if any) to the date of payment shall be immediately due and payable.

        If an Event of Default specified in Section 4.01(g) or 4.01(h) hereof occurs, all unpaid principal of and accrued and unpaid interest (including Liquidated Damages, if any) on the Outstanding Securities shall become and be immediately due and payable, without any declaration or other act on the part of the Trustee or any Holder.

        The Holders of a majority in aggregate principal amount of the Outstanding Securities by written notice to the Trustee may rescind and annul an acceleration and its consequences if:

          (i)  all existing Events of Default, other than the nonpayment of principal of or interest on the Securities that has become due solely because of the acceleration, have been remedied, cured or waived, and

         (ii)  the rescission would not conflict with any judgment or decree of a court of competent jurisdiction;

provided, however, that in the event such declaration of acceleration has been made based on the existence of an Event of Default under Section 4.01(e) hereof and such Event of Default has been remedied, cured or waived in accordance with Section 4.01(e) hereof, then, without any further action by the Holders, such declaration of acceleration shall be rescinded automatically and the consequences of such declaration shall be annulled. No such rescission or annulment shall affect any subsequent Default or impair any right consequent thereon.

        Section 4.03.    Other Remedies.     If an Event of Default with respect to Outstanding Securities occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities.

        The Trustee may maintain a proceeding in which it may prosecute and enforce all rights of action and claims under this Indenture or the Securities, even if it does not possess any of the Securities or does not produce any of them in the proceeding.

21

        Section 4.04.    Waiver of Past Defaults.     The Holders, either (a) through the written consent of not less than a majority in aggregate principal amount of the Outstanding Securities or (b) by the adoption of a resolution, at a meeting of Holders of the Outstanding Securities at which a quorum is present, by the Holders of at least a majority in aggregate principal amount of the Outstanding Securities represented at such meeting, may, on behalf of the Holders of all of the Securities, waive an existing Default or Event of Default, except a Default or Event of Default:

          (i)  in the payment of the principal of or interest (including Liquidated Damages, if any) on any Security (provided, however, that subject to Section 4.02 hereof, the Holders of a majority in aggregate principal amount of the Outstanding Securities may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration);

         (ii)  in respect of the failure to convert any Security in accordance with Article 12; or

        (iii)  in respect of a covenant or provision hereof that, under Section 7.02 hereof, cannot be modified or amended without the consent of the Holder of each Outstanding Security affected.

        Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; provided, however, that no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

        Section 4.05.    Control by Majority.     The Holders, either (a) through the written consent of not less than a majority in aggregate principal amount of the Outstanding Securities, or (b) by the adoption of a resolution, at a meeting of Holders of the Outstanding Securities at which a quorum is present, by the Holders of at least a majority in aggregate principal amount of the Outstanding Securities represented at such meeting, shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that:

          (i)  conflicts with any law or with this Indenture,

         (ii)  the Trustee determines may be unduly prejudicial to the rights of the Holders not joining therein, or

        (iii)  may expose the Trustee to personal liability.

        The Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction.

        Section 4.06.    Limitation on Suit.     No Holder of any Security shall have any right to pursue any remedy with respect to this Indenture or the Securities (including instituting any proceeding, judicial or otherwise, with respect to this Indenture or for the appointment of a receiver or trustee) unless:

          (i)  such Holder has previously given written notice to the Trustee of an Event of Default that is continuing;

         (ii)  the Holders of at least 25% in aggregate principal amount of the Outstanding Securities shall have made written request to the Trustee to pursue the remedy;

        (iii)  such Holder or Holders have offered to the Trustee indemnity satisfactory to it against any costs, expenses and liabilities incurred in complying with such request;

        (iv)  the Trustee has failed to comply with the request for 60 days after its receipt of such notice, request and offer of indemnity; and

         (v)  during such 60-day period, no direction inconsistent with such written request has been given to the Trustee by the Holders of a majority in aggregate principal amount of the Outstanding

22

Securities (or such amount as shall have acted at a meeting pursuant to the provisions of this Indenture);

provided, however, that no one or more of such Holders may use this Indenture to prejudice the rights of another Holder or to obtain preference or priority over another Holder.

        Section 4.07.    Unconditional Rights of Holders to Receive Payment and to Convert.     Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and interest (including Liquidated Damages, if any) on such Security on the Stated Maturity expressed in such Security (or, in the case of redemption, on the Redemption Date, or in the case of the exercise of a Purchase Right or Put Purchase Right, on the Purchase Date or Put Purchase Date, as applicable) and to convert such Security in accordance with Article 12, and to bring suit for the enforcement of any such payment on or after such respective dates and right to convert, and such rights shall not be impaired or affected without the consent of such Holder.

        Section 4.08.    Collection of Indebtedness and Suits for Enforcement by the Trustee.     The Company covenants that if:

          (i)  a Default or Event of Default occurs in the payment of any interest (including Liquidated Damages, if any) on any Security when such interest (including Liquidated Damages, if any) becomes due and payable and such Default or Event of Default continues for a period of 30 days, or

         (ii)  a Default or Event of Default occurs in the payment of the principal of any Security at the Maturity thereof,

the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable (as expressed therein or as a result of any acceleration effected pursuant to Section 4.02 hereof) on such Securities for principal and interest (including Liquidated Damages, if any) and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and on any overdue interest (including Liquidated Damages, if any), in each case at the Interest Rate, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

        If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company, wherever situated.

        If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

        Section 4.09.    Trustee May File Proofs of Claim.     In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or the property of the Company or its creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest (including Liquidated Damages, if any)) shall be entitled and empowered, by intervention in such proceeding or otherwise,

23

(1) to file and prove a claim for the whole amount of principal and interest (including Liquidated Damages, if any) owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders of Securities allowed in such judicial proceeding, and (2) to collect and receive any moneys or other property payable or deliverable on any such claim and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceedings is hereby authorized by each Holder of Securities to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of Securities, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 5.08.

        Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept, or adopt on behalf of any Holder of a Security, any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder of a Security in any such proceeding.

        Section 4.10.    Restoration of Rights and Remedies.     If the Trustee or any Holder of a Security has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders of Securities shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

        Section 4.11.    Rights and Remedies.     Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 2.12, no right or remedy conferred in this Indenture upon or reserved to the Trustee or to the Holders of Securities is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

        Section 4.12.    Delay or Omission Not Waiver.     No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders of Securities may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Securities, as the case may be.

        Section 4.13.    Application of Money Collected.     Any money and property collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money and property on account of principal or interest (including Liquidated Damages, if any), upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

        FIRST: To the payment of all amounts due the Trustee;

        SECOND: To the payment of the amounts then due and unpaid for principal of and interest (including Liquidated Damages, if any) on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according

24

to the amounts due and payable on such Securities for principal and interest (including Liquidated Damages, if any), respectively; and

        THIRD: Any remaining amounts shall be repaid to the Company.

        Section 4.14.    Undertaking for Costs.     All parties to this Indenture agree, and each Holder of any Security by such Holder's acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of the Outstanding Securities, or to any suit instituted by any Holder of any Security for the enforcement of the payment of the principal of or interest (including Liquidated Damages, if any) on any Security on or after the Stated Maturity expressed in such Security (or, in the case of redemption or exercise of a Purchase Right, on or after the Redemption Date) or for the enforcement of the right to convert any Security in accordance with Article 12.

        Section 4.15.    Waiver of Stay or Extension Laws.     The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim to take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE 5
THE TRUSTEE

        Section 5.01.    Certain Duties and Responsibilities.     (a) Except during the continuance of an Event of Default,

          (i)  The Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture or the TIA, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

         (ii)  In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; provided, however, that in the case of any such certificates or opinions that by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates or opinions to determine whether or not, on their face, they conform to the requirements of this Indenture (but need not investigate or confirm the accuracy of any facts stated therein).

        (b)   In case an Event of Default actually known to a Responsible Officer of the Trustee has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs.

25

        (c)   No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

          (i)  This paragraph (c) shall not be construed to limit the effect of paragraph (a) of this Section 5.01;

         (ii)  The Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and

        (iii)  The Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with a direction received by it of the Holders of a majority in principal amount of the Outstanding Securities (or such lesser amount as shall have acted at a meeting pursuant to the provisions of this Indenture) relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture.

        (d)   Whether or not herein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 5.01.

        (e)   No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers. The Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity satisfactory to it against any loss, liability, cost or expense (including, without limitation, reasonable fees of counsel).

        (f)    The Trustee shall not be obligated to pay interest on any money or other assets received by it unless otherwise agreed in writing with the Company. Assets held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

        (g)   The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company, and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

        (h)   The Trustee shall not be deemed to have notice or actual knowledge of any Event of Default or a Registration Default or the obligation of the Company to pay Liquidated Damages unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event that is in fact a Default is received by the Trustee pursuant to Section 14.02 hereof, and such notice references the Securities and this Indenture.

        (i)    The rights, privileges, protections, immunities and benefits given to the Trustee hereunder, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Paying Agent, authenticating agent, Conversion Agent or Registrar acting hereunder.

26

        Section 5.02.    Certain Rights of Trustee.     Subject to the provisions of Section 5.01 hereof and subject to Sections 315(a) through (d) of the TIA:

          (i)  The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

         (ii)  Before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel, or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers' Certificate or the Opinion of Counsel.

        (iii)  The Trustee may act through attorneys and agents and shall not be responsible for the misconduct or negligence of any attorney or agent appointed with due care.

        (iv)  The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith that it reasonably believed to be authorized or within the discretion or rights or powers conferred upon it by this Indenture, unless the Trustee's conduct constitutes negligence.

         (v)  The Trustee may consult with counsel of its selection and the advice of such counsel as to matters of law shall be full and complete authorization and protection in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

        (vi)  Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company.

       (vii)  The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty unless so specified herein.

        Section 5.03.    Individual Rights of Trustee.     The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as such term is defined in Section 310(b) of the TIA), it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee (to the extent permitted under Section 310(b) of the TIA) or resign. Any agent may do the same with like rights and duties. The Trustee is also subject to Section 5.11 and 5.12 hereof.

        Section 5.04.    Money Held in Trust.     Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise expressly agreed with the Company.

        Section 5.05.    Trustee's Disclaimer.     The recitals contained herein and in the Securities (except for those in the certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity, sufficiency or priority of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Company of Securities or the proceeds thereof.

        Section 5.06.    Notice of Defaults.     Within 90 days after the occurrence of any Default or Event of Default hereunder of which the Trustee has received written notice, the Trustee shall give notice to Holders pursuant to Section 14.02 hereof, unless such Default or Event of Default shall have been cured or waived; provided, however, that, except in the case of a Default or Event of Default in the payment of the principal of or interest (including Liquidated Damages, if any), or in the payment of any redemption or purchase obligation, on any Security, the Trustee shall be protected in withholding such notice if and so long as Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders.

27

        Section 5.07.    Reports by Trustee to Holders.     The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required by Section 313 of the TIA at the times and in the manner provided by the TIA.

        A copy of each report at the time of its mailing to Holders shall be filed with the SEC, if required, and each stock exchange, if any, on which the Securities are listed. The Company shall promptly notify the Trustee when the Securities become listed on any stock exchange.

        Section 5.08.    Compensation and Indemnification.     The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as the Company and the Trustee shall from time to time agree in writing and the Company covenants and agrees to pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by it or on its behalf in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ), except to the extent that any such expense, disbursement or advance is due to its negligence or bad faith. When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 4.01 hereof, the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. The Company also covenants to indemnify the Trustee and its officers, directors, employees and agents for, and to hold such Persons harmless against, any loss, liability or expense incurred by them, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder or the performance of their duties hereunder, including the reasonable costs and expenses of defending themselves against or investigating any claim of liability in the premises, except to the extent that any such loss, liability or expense was due to the negligence or willful misconduct of such Persons. The obligations of the Company under this Section 5.08 to compensate and indemnify the Trustee and its officers, directors, employees and agents and to pay or reimburse such Persons for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee. Such additional indebtedness shall be a senior claim to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities, and the Securities are hereby subordinated to such senior claim.

        The Trustee may resign and be discharged from the trust hereby created by so notifying the Company in writing. The Holders of at least a majority in aggregate principal amount of Outstanding Securities may remove the Trustee by so notifying the Trustee and the Company in writing. The Company must remove the Trustee if:

          (i)  the Trustee fails to comply with Section 5.11 hereof or Section 310 of the TIA;

         (ii)  the Trustee becomes incapable of acting;

        (iii)  the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; or

        (iv)  a Custodian or public officer takes charge of the Trustee or its property.

28

        If the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for any reason, the Company shall promptly appoint a successor Trustee. The Trustee shall be entitled to payment of its fees and reimbursement of its expenses while acting as Trustee.

        Any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee if the Trustee fails to comply with Section 5.11 hereof.

        If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation or removal, the resigning or removed Trustee, as the case may be, may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee.

        A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The Company shall mail a notice of the successor Trustee's succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee. Notwithstanding replacement of the Trustee pursuant to this Section 5.09, the Company's obligations under Section 5.08 hereof shall continue for the benefit of the retiring Trustee with respect to expenses, losses and liabilities incurred by it prior to such replacement.

        Section 5.10.    Successor Trustee by Merger, Etc..     Subject to Section 5.11 hereof, if the Trustee consolidates with, merges or converts into, or transfers or sells all or substantially all of its corporate trust business (including the administration of the trust created by this Indenture) to, another corporation or national banking association, the successor entity without any further act shall be the successor Trustee as to the Securities.

        Section 5.11.    Corporate Trustee Required; Eligibility.     The Trustee shall at all times satisfy the requirements of Sections 310(a)(1), (2) and (5) of the TIA. The Trustee shall at all times have (or, in the case of a corporation included in a bank holding company system, the related bank holding company shall at all times have) a combined capital and surplus of at least $100 million as set forth in its (or its related bank holding company's) most recent published annual report of condition. The Trustee is subject to Section 310(b) of the TIA.

        Section 5.12.    Collection of Claims Against the Company.     The Trustee is subject to Section 311(a) of the TIA, excluding any creditor relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated therein.

        Section 10.05.    Effect of Notice of Redemption.     Notice of redemption having been given as provided in Section 10.04 hereof, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and any accrued and unpaid interest (including Liquidated Damages, if any)) such Securities shall cease to bear interest.

37

Upon surrender of any such Security for redemption in accordance with such notice, such Security shall be paid by the Company at the Redemption Price plus any accrued and unpaid interest (including Liquidated Damages, if any); provided, however, that the installments of interest on Securities whose Stated Maturity is prior to or on the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Record Date according to their terms and the provisions of Section 2.01 hereof.

        If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid, bear interest from the Redemption Date at the Interest Rate.

        Section 10.06.    Deposit of Redemption Price.     Prior to or on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent an amount of money sufficient to pay the Redemption Price of all the Securities to be redeemed on that Redemption Date, other than any Securities called for redemption on that date that have been converted prior to the date of such deposit, and any accrued and unpaid interest (including Liquidated Damages, if any) on such Securities.

        If any Security called for redemption is converted, any money deposited with the Trustee or with a Paying Agent or so segregated and held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any Predecessor Security to receive interest as provided in the fourth to last paragraph of Section 2.01 hereof) be paid to the Company upon request of the Company or, if then held by the Company, shall be discharged from such trust.

        Section 10.07.    Securities Redeemed in Part.     Any Security that is to be redeemed only in part shall be surrendered at an office or agency of the Company designated for that purpose pursuant to Section 9.02 hereof (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or the Holder's attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

        Section 10.08.    Conversion Arrangement On Call For Redemption.     In connection with any redemption of Securities, the Company may arrange for the purchase and conversion of any Securities called for redemption by an agreement with one or more investment banks or other purchasers to purchase such Securities by paying to the Trustee in trust for the Holders of the Securities, on or prior to 10:00 a.m. New York City time on the Redemption Date, an amount that, together with any amounts deposited with the Trustee by the Company for the redemption of such Securities, is not less than the Redemption Price of, and any accrued and unpaid interest (including Liquidated Damages, if any) with respect to, such Securities. Notwithstanding anything to the contrary contained in this Article 10, the obligation of the Company to pay the Redemption Price of such Securities shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers. If such an agreement is entered into, any Securities not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such Holders and surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the Business Day prior to the Redemption Date, subject to payment of the above amount as aforesaid. The Trustee shall hold and pay to the Holders whose Securities are selected for redemption any such amount paid to it for purchase and conversion in the same manner as it would moneys deposited with it by the Company for the redemption of Securities. Without the Trustee's prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Securities shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture, and the Company agrees to indemnify the Trustee from, and hold it harmless against, any loss, liability or expense arising out of or in connection

38

with any such arrangement for the purchase and conversion of any Securities between the Company and such purchasers, including the costs and expenses incurred by the Trustee in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture.

ARTICLE 11
PURCHASE OF SECURITIES

        Section 11.01.    Purchase Right Upon Fundamental Change.     (a)    General. In the event that a Fundamental Change shall occur, each Holder shall have the right (the "Purchase Right"), at the Holder's option to require the Company to purchase, and upon the exercise of such right in accordance with this Section 11.01 hereof the Company shall purchase, all of such Holder's Securities not theretofore called for redemption, or any portion of the principal amount thereof that is equal to $1,000 or any whole multiple thereof (provided, however, that no single Security may be purchased in part unless the portion of the principal amount of such Security to be Outstanding after such purchase is equal to $1,000 or whole multiples thereof), on the date (the "Purchase Date") that is not less than 20 nor more than 35 Business Days after the date of the Company Notice at a purchase price equal to 100% of the principal amount of the Securities to be purchased, plus any accrued and unpaid interest (including Liquidated Damages, if any) to, but excluding, the Purchase Date (the "Purchase Price"); provided, however, that if the Purchase Date falls after a Record Date and on or prior to the corresponding Interest Payment Date, the Company shall pay the full amount of any accrued and unpaid interest (including Liquated Damages, if any) payable on such Interest Payment Date to the Holder of record at the close of business on the corresponding Record Date; provided, further, that installments of interest on Securities whose Stated Maturity is prior to or on the Purchase Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Record Date according to their terms and the provisions of Section 2.01 hereof.

The Company shall also deliver a copy of such notice of a Purchase Right to the Trustee. Each notice of a Purchase Right shall state:

          (i)  the Purchase Date;

         (ii)  the date by which the Purchase Right must be exercised;

        (iii)  the Purchase Price;

        (iv)  a description of the procedure that a Holder must follow to exercise a Purchase Right, and the place or places where such Securities are to be surrendered for payment of the Purchase Price;

        (vi)  the Conversion Rate then in effect, the date on which the right to convert the principal amount of the Securities to be purchased will terminate and the place where such Securities may be surrendered for conversion; and

       (vii)  the place or places where such Securities, together with the Notice of Exercise of Purchase Right certificate included in Exhibit A annexed hereto are to be delivered for payment of the Purchase Price.

39

        No failure of the Company to give the foregoing notices or defect therein shall limit any Holder's right to exercise a Purchase Right or affect the validity of the proceedings for the purchase of Securities.

        (c)    Conditions to the Company's Obligation to Purchase.     To exercise a Purchase Right, a Holder shall deliver to the Trustee on or prior to the Purchase Date written notice ("Fundamental Change Purchase Notice") of the Holder's exercise of such right in the form of the Notice of Exercise of Purchase Right certificate included in Exhibit A annexed hereto, which notice shall set forth:

          (i)  the name of the Holder, the principal amount of the Securities to be purchased (and, if any Security is to be purchased in part, the serial number thereof, the portion of the principal amount thereof to be purchased) and a statement that an election to exercise the Purchase Right is being made thereby, and

         (ii)  the applicable Depository procedures or, in the case of Physical Securities, the certificate number(s) of the Holder's Securities with respect to which the Purchase Right is being exercised.

        (d)    Withdrawal of Fundamental Change Purchase Notice.     A Holder may withdraw any Fundamental Change Purchase Notice in whole or in part by a written notice of withdrawal delivered to the Paying Agent prior to the close of business on the applicable Purchase Date. The notice of withdrawal must state:

          (i)  the principal amount of the withdrawn Securities;

         (ii)  the applicable Depositary procedures or, with respect to Physical Securities, the certificate number(s) of the withdrawn Securities; and

        (iii)  the principal amount of Securities, if any, that remains subject to the Fundamental Change Purchase Notice.

        The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof.

        (e)    Payment of Purchase Price by the Company; Effect on Holders of Purchased Securities.     Payment of the Purchase Price for a Security for which a Fundamental Change Purchase Notice has been delivered and not withdrawn is conditioned upon book-entry transfer or delivery of the Security, together with necessary endorsements, to the Paying Agent at its Corporate Trust Office in the Borough of Manhattan, The City of New York, or any other office of the Paying Agent, at any time after delivery of the Fundamental Change Purchase Notice. The Company shall pay the Purchase Price for the Security promptly following the later of the Purchase Date and the time of book-entry transfer or delivery of the Security. If the Paying Agent holds money or securities sufficient to pay the Purchase Price on the relevant Purchase Date, then, on and after the Business Day immediately following the Purchase Date:

          (i)  the purchased Securities will cease to be Outstanding and interest will cease to accrue, and

         (ii)  all other rights of the Holders of such purchased Securities will terminate (other than the right to receive the Purchase Price upon delivery or transfer of such purchased Securities),

        in each case, whether or not book-entry transfer of the purchased Securities is made or whether or not the purchased Securities are delivered to the Paying Agent.

        (f)    If any Security (or portion thereof) surrendered for purchase shall not be so paid on the Purchase Date, the principal amount of such Security (or portion thereof, as the case may be) shall, until paid, bear interest to the extent permitted by applicable law from the Purchase Date at the

40

Interest Rate, and each Security shall remain convertible into Common Stock until the principal of such Security (or portion thereof, as the case may be) shall have been paid or duly provided for.

        (g)   Any Security that is to be purchased only in part shall be surrendered to the Trustee (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, containing identical terms and conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the unpurchased portion of the principal of the Security so surrendered.

        (h)   All Securities delivered for purchase shall be delivered to the Trustee to be canceled at the direction of the Trustee, which shall dispose of the same as provided in Section 2.15 hereof.

        (i)    In connection with any purchase of the Securities pursuant to Sections 11.01, the Company will comply with Rule 13e-4 under the Exchange Act to the extent applicable at that time.

        (j)    No Securities may be purchased by the Company in connection with a Fundamental Change pursuant to this Section 11.01 if the principal amount of the Securities has been accelerated, and such acceleration has not been rescinded, on or prior to the Purchase Date.

        (k)   Whenever in this Indenture (including Sections 2.02, 4.01(a) and 4.07 hereof) or Exhibit A annexed hereto there is a reference, in any context, to the principal of any Security as of any time, such reference shall be deemed to include reference to the Purchase Price payable in respect to such Security to the extent that such Purchase Price is, was or would be so payable at such time, and express mention of the Purchase Price in any provision of this Indenture shall not be construed as excluding the Purchase Price in those provisions of this Indenture when such express mention is not made.

        Section 11.02.    Purchase of Securities by the Company at Option of the Holder.     (a)     General. Each Holder shall have the right (the "Put Purchase Right") to require the Company to purchase all or a portion of its Securities on July 15, 2009, July 15, 2014 and July 15, 2019 (or, if any such date is not a Business Day, on the immediately succeeding Business Day) (each, a "Put Purchase Date"), at 100% of the principal amount of the Securities to be so purchased, plus any accrued and unpaid interest (including Liquidated Damages, if any) to, but excluding, such Put Purchase Date (the "Put Purchase Price").

        (b)    Company Notice.     On or before the twenty-first (21st) Business Day prior to each Put Purchase Date, the Company shall provide to the Trustee, the Paying Agent and to all Holders at their respective addresses as shown on the Register, and to beneficial owners of the Securities where required by applicable law, a notice stating, among other things:

          (i)  the name and address of the Trustee, the Paying Agent and the Conversion Agent; and

         (ii)  the procedures that Holders must follow to require the Company to purchase their Securities.

        Simultaneously with providing such notice, the Company shall publish a notice containing this information in a newspaper of general circulation in The City of New York or publish the information on the Company's website or through such other public medium as the Company may use at that time.

        (c)    Conditions to the Company's Obligation to Purchase.     The Company will be required to purchase only Securities with respect to which each of the following conditions has been satisfied:

          (i)  delivery to the Paying Agent by the Holder of a written notice of purchase (a "Put Purchase Notice") during the period beginning at any time from the opening of business on the

41

date that is twenty-one (21) Business Days prior to the relevant Put Purchase Date until the close of business on the Business Day prior to such Put Purchase Date stating:

        (A)  the applicable Depositary procedures or, in the case of Physical Securities, the certificate number(s) of the Holder's Securities to be delivered for purchase;

        (B)  the portion of the principal amount of Securities to be purchased, in whole multiples of $l,000; and

        (C)  that the Securities are to be purchased by the Company pursuant to paragraph 6(b) of the Securities and this Section 11.02; and

         (ii)  delivery of such Securities to the Trustee or Paying Agent prior to, on or after the Put Purchase Date (together with all necessary endorsements).

        (d)    Withdrawal of Put Purchase Notice.     A Holder may withdraw any Put Purchase Notice in whole or in part by a written notice of withdrawal delivered to the Trustee or the Paying Agent prior to the close of business on the third (3rd) Business Day prior to the applicable Put Purchase Date. The notice of withdrawal must state:

          (i)  the principal amount of the withdrawn Securities;

         (ii)  the applicable Depositary procedures or, with respect to Physical Securities, the certificate number(s) of the withdrawn Securities; and

        (iii)  the principal amount of Securities, if any, that remains subject to the Put Purchase Notice.

        The Trustee or Paying Agent shall promptly notify the Company of the receipt by it of any Put Purchase Notice or written notice of withdrawal thereof.

        The Put Purchase Price shall be so paid pursuant to this Section 11.02 only if the Securities so delivered by the Holder conform in all respects to the description thereof in the related Put Purchase Notice, as determined by the Company in its sole discretion.

        (e)    Payment of Put Purchase Price by the Company; Effect on Holders of Purchased Securities.     Payment of the Put Purchase Price for a Security for which a Put Purchase Notice has been delivered and not withdrawn is conditioned upon book-entry transfer or delivery of the Security, together with necessary endorsements, to the Paying Agent at its Corporate Trust Office in the Borough of Manhattan, The City of New York, or any other office of the Paying Agent, at any time after delivery of the Put Purchase Notice. The Company shall pay the Put Purchase Price to the Paying Agent promptly following the later of the relevant Put Purchase Date or the time of book-entry transfer or delivery of the purchased Securities. If either the Trustee or the Paying Agent holds money or securities sufficient to pay the Put Purchase Price on the Business Day immediately following the Put Purchase Date, then:

          (i)  the purchased Securities will cease to be Outstanding and interest will cease to accrue, and

         (ii)  all other rights of the Holders of such purchased Securities will terminate (other than the right to receive the Put Purchase Price upon delivery or transfer of such purchased Securities),

in each case, whether or not book-entry transfer of the purchased Securities is made or whether or not the purchased Securities are delivered to the Paying Agent.

        (f)    If any Security (or portion thereof) surrendered for purchase shall not be so paid on the Put Purchase Date, the principal amount of such Security (or portion thereof, as the case may be) shall, until paid, bear interest to the extent permitted by applicable law from the Put Purchase Date at the

42

Interest Rate, and each Security shall remain convertible into Common Stock until the principal of such Security (or portion thereof, as the case may be) shall have been paid or duly provided for.

        (g)   Any Security that is to be purchased only in part shall be surrendered to the Trustee (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, containing identical terms and conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the unpurchased portion of the principal of the Security so surrendered.

        (h)   All Securities delivered for purchase shall be delivered to the Trustee to be canceled at the direction of the Trustee, which shall dispose of the same as provided in Section 2.15 hereof.

        (i)    In connection with any purchase of the Securities pursuant to this Section 11.02, the Company will comply with Rule 13e-4 under the Exchange Act to the extent applicable at that time.

        (j)    No Securities may be purchased by the Company pursuant to this Section 11.02 if the principal amount of the Securities has been accelerated, and such acceleration has not been rescinded, on or prior to the relevant Put Purchase Date.

        (k)   Whenever in this Indenture (including Sections 2.02, 4.01(a) and 4.07 hereof) or Exhibit A annexed hereto there is a reference, in any context, to the principal of any Security as of any time, such reference shall be deemed to include reference to the Put Purchase Price payable in respect to such Security to the extent that such Put Purchase Price is, was or would be so payable at such time, and express mention of the Put Purchase Price in any provision of this Indenture shall not be construed as excluding the Put Purchase Price in those provisions of this Indenture when such express mention is not made.

ARTICLE 12
CONVERSION OF SECURITIES

        Section 12.01.    Conversion Right and Conversion Rate.     (a) (i) Subject to and upon: (A)  compliance with the provisions of this Article and (B) the occurrence of one or more of the conditions set forth in paragraph 7(d) of the Securities, at the option of the Holder thereof, any Security or any portion of the principal amount thereof that is $1,000 or a multiple of $1,000 may be converted at the principal amount thereof, or of such portion thereof, into the number of duly authorized, fully paid and nonassessable shares of Common Stock at the Conversion Rate in effect at the time of conversion. Such conversion right shall expire at the close of business on the Business Day immediately preceding July 15, 2024.

         (ii)  If a Holder of Securities elects to convert its Securities in connection with a specified corporate transaction pursuant to Section 7(d)(iv)(B) of the Securities that occurs on or prior to July 15, 2009, and the corporate transaction also constitutes a transaction described in clause (2) of the definition of Change of Control, such Holder shall be entitled to receive, in addition to a number of shares of Common Stock equal to the Conversion Rate per $1,000 principal amount of Securities, an additional number of shares of Common Stock (the "Additional Shares") as described below; provided that if the Stock Price is equal to or greater than $50.00 or less than $8.23 (subject in each case to adjustment as described below), the number of Additional Shares shall be zero. The number of Additional Shares shall be determined by reference to the table attached as Schedule A hereto, based on the Effective Date and the Stock Price; provided that if the Stock Price is between two Stock Price amounts in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a

43

straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the two dates, as applicable, based on a 365-day year. The Additional Shares will be delivered to Holders who elect to convert their Securities in connection with an applicable Change of Control on the later of (i) five Business Days following the Effective Date or (ii) the conversion settlement date for those Securities.

        The Stock Prices set forth in the first row of the table in Schedule A hereto and set forth in the proviso in the first sentence of the preceding paragraph shall be adjusted as of any date on which the Conversion Rate of the Securities is adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The Company's obligation to deliver Additional Shares shall be subject to adjustment in the same manner as the Conversion Rate as set forth Section 12.04 and Section 12.11.

        Notwithstanding the foregoing, in no event will the total number of shares of Common Stock issuable upon conversion exceed 121.5067 per $1,000 principal amount of Securities, subject to adjustments in the same manner as the Conversion Rate as set forth in Section 12.04 and Section 12.11.

        Promptly following the Effective Date, the Company shall calculate the Stock Price and the number of Additional Shares based on the applicable Stock Price and Effective Date. No less than five Business Days following the Effective Date, the Company shall notify the Trustee of the results of such calculations and notify the Holders of the Stock Price, the number of Additional Shares per $1,000 principal amount of Securities. The Company shall issue a press release containing the information described in this paragraph and publish such information on its website.

        (b)   In case a Security or portion thereof is called for redemption, such conversion right in respect of the Security or the portion so called, shall expire at the close of business on the Business Day immediately preceding the Redemption Date, unless the Company defaults in making the payment due upon redemption. If a Holder exercises its Purchase Right or Put Purchase Right with respect to a Security or portion thereof, such conversion right in respect of the Security or portion thereof shall expire at the close of business on the Business Day preceding the Purchase Date or Put Purchase Date, as applicable.

        (c)   Each $1,000 principal amount of the Securities shall be convertible into 86.7905 shares of Common Stock (herein called the "Conversion Rate"), subject to adjustment in certain instances as provided in paragraphs (a), (b), (c), (d), (e), (f), (h) and (m) of Section 12.04 hereof.

        Section 12.02.    Exercise of Conversion Right.     To exercise the conversion right, the Holder of any Security to be converted shall surrender such Security duly endorsed or assigned to the Company or in blank, at the office of any Conversion Agent, accompanied by a duly signed conversion notice substantially in the form attached to the Security to the Company stating that the Holder elects to convert such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted.

        Any Security surrendered for conversion during the period beginning on the close of business on any Regular Record Date and ending with the opening of business on the corresponding interest Payment Date shall be accompanied by payment of an amount equal to the interest (excluding Liquidated Damages, if any) to be received on such Interest Payment Date on the principal amount of the Security being surrendered for conversion. Notwithstanding the foregoing, any Holder that surrenders for conversion any Security (a) that has been called for redemption by the Company in a notice of redemption given by the Company pursuant to Section 10.04 hereof on a Redemption Date after such Regular Record Date and on or prior to the next succeeding Interest Payment Date, (b) with

44

respect to which the Company has specified a Purchase Date that is after such Regular Record Date and on or prior to the next succeeding Interest Payment Date or (c) on which Defaulted Interest is payable at the time of conversion, but only to the extent of such Defaulted Interest, need not make the payment referred to in the preceding sentence. In either case described in clause (a) or clause (b) above, such Holder shall be entitled to receive (and retain) the interest to be received on such Interest Payment Date on the principal amount of the Security being surrendered for conversion.

        Securities shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Securities for conversion in accordance with the foregoing provisions, and at such time the rights of the Holders of such Securities as Holders shall cease, and the Person or Persons entitled to receive the Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such Common Stock at such time. Except as provided above in this Section 12.02, no adjustment shall be made for interest and Liquidated Damages, if any, accrued on any Security converted or for dividends on any shares issued upon the conversion of such Security as provided in this Article 12. As promptly as practicable on or after the conversion date, but in no event later than the fifth Business Day thereafter, the Company shall cause to be issued and delivered to such Conversion Agent a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with payment in lieu of any fraction of a share as provided in Section 12.03 hereof.

        In the case of any Security that is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Security or Securities of authorized denominations in aggregate principal amount equal to the unconverted portion of the principal amount of such Securities.

        If shares of Common Stock to be issued upon conversion of a Restricted Security, or Securities to be issued upon conversion of a Restricted Security in part only, are to be registered in a name other than that of the Holder of such Restricted Security, such Holder must deliver to the Conversion Agent a certificate in substantially the form set forth in the form of Security set forth in Exhibit A annexed hereto, dated the date of surrender of such Restricted Security and signed by such Holder, as to compliance with the restrictions on transfer applicable to such Restricted Security. Neither the Trustee nor any Conversion Agent, Registrar or Transfer Agent shall be required to register in a name other than that of the Holder shares of Common Stock or Securities issued upon conversion of any such Restricted Security not so accompanied by a properly completed certificate.

        The Company hereby initially appoints the Trustee as the Conversion Agent.

        Delivery to the Holder of Securities of the full number of shares of Common Stock into which the Securities are convertible pursuant to the terms of this Article 12 shall be deemed to satisfy the Company's obligation with respect to such Securities. Accordingly, any accrued but unpaid interest shall be deemed to be paid in full upon conversion, rather than cancelled, extinguished or forfeited.

        Section 12.03.    Fractional Shares.     No fractional shares of Common Stock shall be issued upon conversion of any Security or Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock that would otherwise be issued upon conversion of any Security or Securities (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction (calculated to the nearest one-100th of a share) in an amount equal to the same fraction of the Sale Price of the Common Stock as of the Trading Day preceding the date of conversion.

45

        Section 12.04.    Adjustment of Conversion Rate.     The Conversion Rate shall be subject to adjustments, calculated by the Company, from time to time as follows:

        (a)   In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be increased by multiplying such Conversion Rate by a fraction:

          (i)  the numerator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the Record Date (as defined in Section 12.04(g)) fixed for such determination plus the total number of shares constituting such dividend or other distribution, and

         (ii)  the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on such Record Date fixed for such determination.

Such increase shall become effective immediately after the opening of business on the day following the Record Date. If any dividend or distribution of the type described in this Section 12.04(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

        (b)   In case the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

        (c)   In case the Company shall issue rights or warrants to all holders of its outstanding shares of Common Stock entitling them to subscribe for or purchase shares of Common Stock for a period expiring 45 days or less from the date of issuance of such rights or warrants (or securities convertible into Common Stock) at a price per share (or having a conversion price per share) less than the Current Market Price (as defined in Section 12.04(g)) on the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect at the opening of business on the date after such Record Date by a fraction:

          (i)  the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the Record Date plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible securities so offered are convertible), and

         (ii)  the denominator of which shall be the number of shares of Common Stock outstanding on the close of business on the Record Date plus the number of shares that the aggregate offering price of the total number of shares so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered) would purchase at such Current Market Price.

Such adjustment shall become effective immediately after the opening of business on the day following the Record Date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock (or securities convertible into Common Stock) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or

46

warrants the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible into Common Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. Notwithstanding the foregoing, after a period of 45 days from the date of issuance of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible into Common Stock) actually delivered during such period. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, the value of such consideration if other than cash, to be determined by the Board of Directors.

        (d)   In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company (other than any dividends or distributions to which Section 12.04(a) applies) or evidences of its indebtedness, cash or other assets, including securities, but excluding (1) any rights or warrants referred to in Section 12.04(c), (2) any stock, securities or other property or assets (including cash) distributed in connection with a reclassification, change, merger, consolidation, binding share exchange, combination, sale, lease or other transfer to which Section 12.11 hereof applies and (3) dividends and distributions paid exclusively in cash (the distributed securities not excluded by the foregoing clauses (1), (2) and (3) hereinafter in this Section 12.04(d) called the "securities"), then, in each such case, subject to the second succeeding paragraph of this Section 12.04(d), the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the Record Date (as defined in Section 12.04(g)) with respect to such distribution by a fraction:

          (i)  the numerator of which shall be the Current Market Price (determined as provided in Section 12.04(g)) on such date, and

         (ii)  the denominator of which shall be such Current Market Price on such date less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) on such date of the portion of the shares of capital stock, evidences of indebtedness, cash or other assets, including securities, so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of the Common Stock outstanding on the Record Date).

        Such increase shall become effective immediately prior to the opening of business on the day following the Record Date. However, in the event that the then fair market value (as so determined) of the portion of the shares of capital stock, evidences of indebtedness, cash or other assets, including securities, so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of a Security (or any portion thereof) the amount of shares of capital stock, evidences of indebtedness, cash or other assets, including securities, such Holder would have received had such Holder converted such Security (or portion thereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

47

        In the event that the Company makes a distribution to all holders of the Common Stock consisting of capital stock of, or similar equity interests in, a Subsidiary or other business unit of the Company, the Conversion Rate will be adjusted based on the market value of the securities so distributed relative to the market value of the Common Stock, in each case based on the average of the Sale Prices of those securities for each of the 10 Trading Days commencing on and including the fifth Trading Day after the date on which "ex-distribution trading" commences for such dividend or distribution on the Nasdaq National Market or such other national or regional exchange or market on which the securities are then listed or quoted.

        If the Board of Directors determines the fair market value of any distribution for purposes of this Section 12.04(d) by reference to the actual or when issued trading market for any securities comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the "Reference Period") used in computing the Current Market Price pursuant to Section 12.04(g) to the extent possible, unless the Board of Directors in a Board Resolution determines in good faith that determining the fair market value during the Reference Period would not be in the best interest of the Holder.

        Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company's capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events ("Trigger Event"):

          (i)  are deemed to be transferred with such shares of Common Stock,

         (ii)  are not exercisable, and

        (iii)  are also issued in respect of future issuances of Common Stock

shall be deemed not to have been distributed for purposes of this Section 12.04(d) (and no adjustment to the Conversion Rate under this Section 12.04(d) will be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different securities, evidences of indebtedness or other assets or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Rate under this Section 12.04(d):

        (1)   in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of Common Stock with respect to such rights or warrant (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and

        (2)   in the case of such rights or warrants all of which shall have expired or been terminated without exercise, the Conversion Rate shall be readjusted as if such rights and warrants had never been issued.

        For purposes of this Section 12.04(d) and Section 12.04(a), 12.04(b) and 12.04(c), any dividend or distribution to which this Section 12.04(d) is applicable that also includes shares of Common Stock, a subdivision or combination of Common Stock to which Section 12.04(b) applies, or rights or warrants

48

to subscribe for or purchase shares of Common Stock to which Section 12.04(c) applies (or any combination thereof), shall be deemed instead to be:

        (1)   a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants other than such shares of Common Stock, such subdivision or combination or such rights or warrants to which Section 12.04(a), 12.04(b) and 12.04(c) apply, respectively (and any Conversion Rate increase required by this Section 12.04(d) with respect to such dividend or distribution shall then be made), immediately followed by

        (2)   a dividend or distribution of such shares of Common Stock, such subdivision or combination or such rights or warrants (and any further Conversion Rate increase required by Section 12.04(a), 12.04(b) and 12.04(c) with respect to such dividend or distribution shall then be made), except:

        (A)  the Record Date of such dividend or distribution shall be substituted as (x) "the date fixed for the determination of stockholders entitled to receive such dividend or other distribution", "Record Date fixed for such determination" and "Record Date" within the meaning of Section 12.04(a), (y) "the day upon which such subdivision becomes effective" and "the day upon which such combination becomes effective" within the meaning of Section 12.04(b), and (z) "the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants," such "Record Date," "the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants" and "such dated fixed for the determination of stockholders entitled to receive such rights or warrants" within the meaning of Section 12.04(c), and

        (B)  any shares of Common Stock included in such dividend or distribution shall not be deemed "outstanding at the close of business on the Record Date fixed for such determination" within the meaning of Section 12.04(a) and any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend or distribution.

        (e)   In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any cash that is distributed upon a reclassification, change, merger, consolidation, binding share exchange, combination, sale, lease or other transfer to which Section 12.11 hereof applies), then and in each such case, immediately after the close of business on the Record Date with respect to such distribution, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on such Record Date by a fraction:

          (i)  the numerator of which shall be equal to the Current Market Price on the Record Date, and

         (ii)  the denominator of which shall be equal to the Current Market Price on such date less an amount equal to the quotient of (x) the aggregate amount of the cash distribution and (y) the number of shares of Common Stock outstanding on the Record Date.

In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

49

        (f)    (i) In case a tender or exchange offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of Common Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) that as of the last time (the "Expiration Time") tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Current Market Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Expiration Time by a fraction:

        (A)  the numerator of which shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time multiplied by the Sale Price of the Common Stock on the Trading Day next succeeding the Expiration Time, and

        (B)  the denominator shall be the product of the number of shares of Common Stock outstanding (including any Purchased Shares) at the Expiration Time and the Sale Price of the Common Stock on the Trading Day next succeeding the Expiration Time.

        Such increase (if any) shall become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made. If the application of this Section 12.04(f)(i) to any tender or exchange offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender or exchange offer under this Section 12.04(f)(i).

         (ii)  In case of a tender or exchange offer made by a Person other than the Company or any Subsidiary for an amount that increases the offeror's ownership of Common Stock to more than twenty-five percent (25%) of the Common Stock outstanding and shall involve the payment by such Person of consideration per share of Common Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) that as of the last time (the "Offer Expiration Time") tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended) exceeds the Sale Price per share of the Common Stock on the Trading Day next succeeding the Offer Expiration Time, and in which, as of the Offer Expiration Time the Board of Directors is not recommending rejection of the offer, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Offer Expiration Time by a fraction,

        (A)  the numerator of which shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Offer Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Accepted Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any

50

Accepted Purchased Shares) at the Offer Expiration Time and the Sale Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time, and

        (B)  the denominator of which shall be the number of shares of Common Stock outstanding (including any Accepted Purchased Shares) at the Offer Expiration Time multiplied by Sale Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time,

such adjustment to become effective immediately prior to the opening of business on the day following the Offer Expiration Time. In the event that such Person is obligated to purchase shares pursuant to any such tender or exchange offer, but such Person is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the adjustment described in this Section 12.04(f)(ii) shall not be made if, as of the Offer Expiration Time, the offering documents with respect to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Section 12.11.

        (g)   For purposes of this Section 12.04, the following terms shall have the meanings indicated:

        (1)   "Current Market Price" of the Common Stock on any day means the average of the Sale Price of the Common Stock for each of the 10 consecutive Trading Days ending on the earlier of the day in question and the day before the "ex-date" with respect to the issuance or distribution requiring such computation.

        For purposes of this paragraph, the term "ex" date, when used:

        (A)  with respect to any issuance or distribution, means the first date on which the shares of the Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such issuance or distribution;

        (B)  with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and

        (C)  with respect to any tender or exchange offer, means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time of such offer.

        Notwithstanding the foregoing, whenever successive adjustments to the Conversion Rate are called for pursuant to this Section 12.04, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 12.04 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.

        (1)   "fair market value" shall mean the amount that a willing buyer would pay a willing seller in an arm's length transaction.

        (2)   "Record Date" shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

        (h)   The Company may make such increases in the Conversion Rate, in addition to those required by Section 12.04(a), (b), (c), (d), (e) or (f), as the Board of Directors considers to be advisable to avoid

51

or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes.

        The Company may from time to time, to the extent permitted by law and subject to applicable rules of the Nasdaq National Market, increase the Conversion Rate of the Securities by any amount for any period of at least 20 days. In such event, the Company shall give at least 15 days notice of such increase. The Company may make such increases in the Conversion Rate, in addition to those set forth above, as the Board of Directors deems advisable to avoid or diminish any income tax to Holders of the Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes.

        (i)    No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Price; provided, however, that any adjustments that by reason of this Section 12.04(i) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. Notwithstanding the foregoing, all such carried forward adjustments shall be made at the time the Company mails a notice of redemption or notifies Holders of the Securities of a specified corporate transaction that would entitle them to convert their Securities and thereafter any Conversion Rate adjustment shall be made without regard to the 1% threshold described in the preceding sentence.

        Except as otherwise provided in this Article 12, no adjustment need be made for the issuance of Common Stock or any securities convertible into or exchangeable for Common Stock or that carry the right to purchase any of the foregoing. All calculations under this Article 12 shall be made by the Company and shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be. No adjustment need be made for a change in the par value or no par value of the Common Stock.

        (j)    To the extent the Holders of Securities may participate on an as-converted basis equally with the holders of Common Stock in any event or occurrence, then Section 12.04 hereof shall not apply to such event on occurrence.

        (k)   In any case in which this Section 12.04 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any Security converted after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 12.03 hereof.

        (l)    For purposes of this Section 12.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

        (m)  The Company has entered into a Preferred Shares Rights Agreement, dated as of December 7, 1988, as amended and restated effective September 20, 1999, by and between the Company and ChaseMellon Shareholder Services, L.L.C. (as amended from time to time, the "Rights Agreement"). Under the Rights Agreement, preference share purchase rights (the "Rights") have been, and may in the future be, issued in respect of shares of Common Stock. Each share of Common Stock issued upon conversion of Securities pursuant to this Article 12 shall be entitled to receive the appropriate number of Rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as provided by and subject to the terms of

52

the Rights Agreement as in effect at the time of such conversion. If hereafter the Rights separate from the Common Stock in accordance with the provisions of the Rights Agreement so that a Holder of Securities would thereafter not be entitled to receive any Rights in respect of the Common Stock issuable upon conversion of such Security, the Conversion Rate will be adjusted as provided in Section 12.04(d) on the separation date.

        Section 12.05.    Notice of Adjustments of Conversion Rate.     Whenever the Conversion Rate is adjusted as herein provided (other than in the case of an adjustment pursuant to the second paragraph of Section 12.04(h) for which the notice required by such paragraph has been provided), the Company shall promptly file with the Trustee and any Conversion Agent other than the Trustee an Officers' Certificate setting forth the adjusted Conversion Rate and showing in reasonable detail the facts upon which such adjustment is based. Unless and until a Responsible Officer of the Trustee receives an Officers' Certificate describing an adjustment of the Conversion Price, the Trustee may assume without inquiry that no such adjustment has been made. Promptly after delivery of such Officers' Certificate, the Company shall prepare a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective, and shall mail such notice to each Holder at the address of such Holder as it appears in the Register within 20 days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

        Section 12.06.    Notice Prior to Certain Actions.     In case at any time after the date hereof:

        (1)   the Company shall declare a dividend (or any other distribution) on its Common Stock payable otherwise than in cash out of its capital surplus or its consolidated retained earnings;

        (2)   the Company shall authorize the granting to the holders of its Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class (or of securities convertible into shares of capital stock of any class) or of any other rights;

        (3)   there shall occur any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, a change in par value, a change from par value to no par value or a change from no par value to par value), or any merger, consolidation, binding share exchange or combination to which the Company is a party and for which approval of any shareholders of the Company is required, or the sale, lease or other transfer in one transaction or a series of related transactions to another corporation of the consolidated assets of the Company and its Subsidiaries, substantially as an entirety; or

        (4)   there shall occur the voluntary or involuntary dissolution, liquidation or winding up of the Company;

the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of securities pursuant to Section 9.02 hereof, and shall cause to be provided to the Trustee and all Holders in accordance with Section 14.02 hereof, at least 20 days (or 10 days in any case specified in clause (1) or (2) above) prior to the applicable record or effective date hereinafter specified, a notice stating:

        (A)  the date on which a record is to be taken for the purpose of such dividend, distribution, rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights or warrants are to be determined, or

        (B)  the date on which such reclassification, merger, consolidation, binding share exchange, combination, sale, lease, transfer, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property

53

deliverable upon such reclassification, merger, consolidation, binding share exchange, sale, lease, transfer, dissolution, liquidation or winding up.

        Neither the failure to give such notice nor any defect therein shall affect the legality or validity of the proceedings or actions described in clauses (1) through (4) of this Section 12.06.

        Section 12.07.    Company to Reserve Common Stock.     The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Securities, the full number of shares of fully paid and non-assessable Common Stock then issuable upon the conversion of all Outstanding Securities.

        Section 12.08.    Tax on Conversions.     Except as provided in the next sentence, the Company will pay any and all taxes (other than taxes on income) and duties that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. A Holder delivering a Security for conversion shall be liable for and will be required to pay any tax or duty that may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless the Person requesting such issue has paid to the Company the amount of any such tax or duty, or has established to the satisfaction of the Company that such tax or duty has been paid.

        Section 12.09.    Covenant as to Common Stock.     The Company covenants that all shares of Common Stock that may be issued upon conversion of Securities will upon issue be fully paid and nonassessable and, except as provided in Section 12.08, the Company will pay all taxes, liens and charges with respect to the issue thereof.

        Section 12.10.    Cancellation of Converted Securities.     All Securities delivered for conversion shall be delivered to the Trustee to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 2.09.

        Section 12.11.    Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale.     If any of following events occur, namely:

          (i)  any recapitalization, reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination),

         (ii)  any merger, consolidation, binding share exchange or combination of the Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock or

        (iii)  any sale, lease or other transfer of the consolidated assets of the Company and its Subsidiaries, substantially as an entirety, to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock,

the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that each Security shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) that such Holder would have been entitled to receive upon such recapitalization, reclassification, change, merger, consolidation, binding share exchange, combination, sale, lease or other transfer had such Securities been converted into Common Stock immediately prior to such recapitalization, reclassification, change, merger, consolidation, binding share exchange, combination, sale, lease or other transfer assuming such holder of Common Stock did not exercise its

54

rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such recapitalization, reclassification, change, merger, consolidation, binding share exchange, combination, sale, lease or other transfer (provided that, if the kind or amount of securities, cash or other property receivable upon such recapitalization, reclassification, change, merger, consolidation, binding share exchange, combination, sale, lease or other transfer is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised ("Non-Electing Share"), then for the purposes of this Section 12.11 the kind and amount of securities, cash or other property receivable upon such recapitalization, reclassification, change, merger, consolidation, binding share exchange, combination, sale, lease or other transfer for each Non-Electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-Electing Shares). Such supplemental indenture shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 12. If, in the case of any such recapitalization, reclassification, change, merger, consolidation, binding share exchange, combination, sale, lease or other transfer, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such recapitalization, reclassification, change, merger, consolidation, binding share exchange, combination, sale, lease or other transfer, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the Purchase Rights and Put Purchase Rights set forth in Article 11 hereof.

        The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the Register, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

        The above provisions of this Section 12.11 shall similarly apply to successive recapitalizations, reclassifications, mergers, consolidations, binding share exchanges, combinations, sales, leases or other transfers.

        If this Section 12.11 applies to any event or occurrence, Section 12.04 hereof shall not apply.

        Section 12.12.    Responsibility of Trustee for Conversion Provisions.     The Trustee, subject to the provisions of Section 5.01 hereof, and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Securities to determine whether any facts exist that may require any adjustment of the Conversion Price, or with respect to the nature or intent of any such adjustments when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. Neither the Trustee, subject to the provisions of Section 5.01 hereof, nor any Conversion Agent shall be accountable with respect to the validity or value (of the kind or amount) of any Common Stock, or of any other securities or property, that may at any time be issued or delivered upon the conversion of any Security; and it or they do not make any representation with respect thereto. Neither the Trustee, subject to the provisions of Section 5.01 hereof, nor any Conversion Agent shall be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of stock or share certificates or other securities or property upon the surrender of any Security for the purpose of conversion; and the Trustee, subject to the provisions of Section 5.01 hereof, and any Conversion Agent shall not be responsible or liable for any failure of the Company to comply with any of the covenants of the Company contained in this Article.

        Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders of Securities signing such instrument or instruments and so voting at such meeting. Proof of execution of any such instrument or of a writing appointing any such agent or proxy, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 5.01 hereof) conclusive in favor of the Trustee and the Company if made in the manner provided in this Section.

        (d)   Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of the Holders of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

        (e)   The Company may, but is not obligated to, fix a record date (which need not be within the time limits otherwise prescribed by Trust Indenture Act Section 316(c)) for the purpose of determining the Holders entitled to act with respect to any amendment or waiver or in any other regard, except that during the continuance of an Event of Default, only the Trustee may set a record date as to notices of default, any declaration or acceleration or any other remedies or other consequences of the Event of Default. If a record date is fixed, those Persons that were Holders at such record date and only those Persons will be entitled to act, or to revoke any previous act, whether or not those Persons continue to be Holders after the record date. No act with respect to any amendment or waiver or in any other regard under this Indenture will be effective for more than 90 days after the record date for the taking of such action.

57

should know, that the Opinion of Counsel with respect to the matters upon which such certificate or opinion is based is erroneous. Any such Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or representations with respect to such matters are erroneous.

        Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

        Upon any application or request by the Company to the Trustee to take any action under any provision of this Indenture, the Company shall furnish to the Trustee an Officers' Certificate stating that all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with, except that in the case of any such application or request as to which the furnishing of such document is specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate need be furnished.

        Section 14.06.    Statements Required in Certificate or Opinion.     Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include:

        (1)   a statement that each individual signing such certificate or opinion on behalf of the Company has read such covenant or condition and the definitions herein relating thereto;

        (2)   a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

        Section 14.10.    Benefits of Indenture.     Nothing contained in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder, the holders of Senior Debt and the Holders of Securities, any benefit or legal or equitable right, remedy or claim under this Indenture.

        Section 14.11.    Governing Law.     THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

        Section 14.12.    Counterparts.     This instrument maybe executed in any number of counterparts, each of which when so executed shall be deemed to be an original but all such counterparts shall together constitute but one and the same instrument.

58

        Section 14.13.    Legal Holidays.     In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security or the last day on which a Holder of a Security has a right to convert such Security shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Securities) payment of interest (including Liquidated Damages, if any) or principal or conversion of the Securities, need not be made on such day, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date or Redemption Date or at the Stated Maturity or on such last day for conversion; provided, however, that in the case that payment is made on such succeeding Business Day, no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

        Section 14.14.    Recourse Against Others.     No recourse for the payment of the principal of or interest (including Liquidated Damages, if any) on any Security, or for any claim based thereon or otherwise in respect thereof, shall be had against any incorporator, shareholder, officer or director, as such, past, present or future, of the Company or of any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance thereof and as part of the consideration for the issue thereof, expressly waived and released.

[REVERSE OF SECURITY]

NOVELL, INC.

0.50% Convertible Senior Debenture due 2024

        Capitalized terms used herein but not defined shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

        1.    Principal and Interest.     Novell, Inc., a Delaware corporation (the "Company"), promises to pay interest on the principal amount of this Security at the Interest Rate from the date of issuance until repayment at Maturity, redemption or repurchase. The Company shall pay interest on this Security semiannually in arrears on January 15 and July 15 of each year (each an "Interest Payment Date"), commencing January 15, 2005.

        Interest on this Security shall be computed on the basis of a 360-day year of twelve 30-day months and for any period shorter than a full semiannual period for which interest is calculated, on the basis of a 30-day month and, for such periods of less than a month, the actual number of days elapsed over a 30-day month.

        Subject to Section 2.17 of the Indenture, a Holder of any Security at the close of business on a Regular Record Date shall be entitled to receive interest on such Security on the corresponding Interest Payment Date. A Holder of any Security that is converted after the close of business on a Regular Record Date and prior to the corresponding Interest Payment Date shall be entitled to receive interest (including Liquidated Damages, if any) on the principal amount of such Security, notwithstanding the conversion of such Security prior to such Interest Payment Date. However, any such Holder that surrenders any such Security for conversion during the period between the close of business on such Regular Record Date and ending with the opening of business on the corresponding Interest Payment Date shall be required to pay the Company an amount equal to the interest (excluding Liquidated Damages, if any) on the principal amount of such Security so converted, that is payable by the Company to such Holder on such Interest Payment Date, at the time such Holder surrenders such Security for conversion. Notwithstanding the foregoing, any such Holder that surrenders for conversion any Security (a) that has been called for redemption by the Company in a notice of redemption given by the Company pursuant to Section 10.04 of the Indenture on a Redemption Date after such Regular Record Date and on or prior to the next succeeding Interest Payment Date, (b) with respect to which the Company has specified a Purchase Date that is after such Regular Record Date and on or prior to the next succeeding Interest Payment Date or (c) on which Defaulted Interest is payable at the time of conversion, but only to the extent of such Defaulted Interest, need not make the payment referred to in the preceding sentence. In either case described in clause (a) or clause (b) above, such Holder shall be entitled to receive (and retain) the interest to be received on such Interest Payment Date on the principal amount of the Security being surrendered for conversion.

        The Company shall pay Liquidated Damages in accordance with the terms of the Registration Rights Agreement.

        Any amount of Liquidated Damages shall be payable in cash semiannually, in arrears, on each Interest Payment Date and shall cease to accrue on the earlier of (i) the day after the end of the Shelf Registration Period (as defined in the Registration Rights Agreement) and (ii) the date the Registration Default is cured. The Holder of this Security is entitled to the benefits of the Registration Rights Agreement.

        2.    Method of Payment.     Interest on any Security that is payable, and is to be punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name that

A-5

Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

        Principal of and interest on, Global Securities shall be payable to the Depositary in immediately available funds.

        Principal of Physical Securities shall be payable at the office or agency of the Company maintained for such purpose, initially the Corporate Trust Office of the Trustee. Interest on Physical Securities shall be payable by (i) U.S. Dollar check drawn on a bank located in the city where the Corporate Trust Office of the Trustee is located mailed to the address of the Person entitled thereto as such address shall appear in the Register, or (ii) upon application to the Registrar not later than the relevant Record Date by a Holder of an aggregate principal amount of Securities in excess of $5,000,000, wire transfer in immediately available funds.

        3.    Paying Agent and Registrar.     Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change the Paying Agent or Registrar without notice to any Holder.

        4.    Indenture.     The Company issued this Security under an Indenture, dated as of July 2, 2004 (the "Indenture"), between the Company and Wells Fargo Bank, National Association, as trustee (the "Trustee"). The terms of this Security include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended ("TIA"). This Security is subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the Indenture shall control.

        5.    Optional Redemption.     This Security is not redeemable prior to July 20, 2009. This Security may be redeemed in whole or in part, upon not less than 30 nor more than 60 days' notice, at any time on or after July 20, 2009, at the option of the Company, at a redemption price equal to 100% of the principal amount of the Securities plus any accrued and unpaid interest (including Liquidated Damages, if any) but not paid prior to, but excluding, the Redemption Date.

        If fewer than all the Securities are to be redeemed, the Trustee shall select the particular Securities to be redeemed from the Outstanding Securities by the methods as provided in the Indenture. If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed to be the portion selected for redemption (provided, however, that the Holder of such Security so converted and deemed redeemed shall not be entitled to any additional interest payment as a result of such deemed redemption than such Holder would have otherwise been entitled to receive upon conversion of such Security). Securities that have been converted during a selection of Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such selection.

        On and after the Redemption Date, interest shall cease to accrue on Securities or portions of Securities called for redemption, unless the Company defaults in the payment of the Optional Redemption Price and any accrued and unpaid interest.

        Notice of redemption shall be given by the Company to the Holders as provided in the Indenture.

        6.    Purchase Rights.

        (a)    Purchase Right Upon a Fundamental Change.    If a Fundamental Change occurs, the Holder of Securities, at the Holder's option, shall have the right, in accordance with the provisions of the Indenture, to require the Company to purchase the Securities (or any portion of the principal amount hereof that is at least $1,000 or a multiple thereof; provided, however, that the portion of the principal amount of this Security to be Outstanding after such purchase is at least equal to $1,000) at a purchase price equal to 100% of the principal amount of the Securities to be

A-6

purchased, plus any accrued and unpaid interest (including Liquidated Damages, if any) to, but excluding, the Purchase Date (the "Purchase Price"); provided, however, that if the Purchase Date falls after a Record Date and on or prior to the corresponding Interest Payment Date, the Company shall pay the full amount of any accrued and unpaid interest (including Liquated Damages, if any) payable on such Interest Payment Date to the Holder of record at the close of business on the corresponding Record Date; provided, further, that installments of interest on Securities whose Stated Maturity is prior to or on the Purchase Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Record Date according to their terms and the provisions of Section 2.01 of the Indenture.

        A Company Notice shall be given by the Company to the Holders as provided in the Indenture. To exercise a Purchase Right, a Holder must deliver to the Trustee a written notice as provided in the Indenture.

        (b)    Purchase by the Company at the Option of the Holder.    Subject to the terms and conditions of the Indenture, each Holder shall have the right to require the Company to purchase all or a portion of their Securities on July 15, 2009, July 15, 2014 and July 15, 2019 (or, if any such date is not a Business Day, on the immediately succeeding Business Day) (each, a "Put Purchase Date"), at 100% of the principal amount of the Securities to be so purchased, plus any accrued and unpaid interest (including Liquidated Damages, if any), if any, to, but excluding, such Put Purchase Date (the "Put Purchase Price"). On or before the twenty-first (21st) Business Day prior to each Put Purchase Date, the Company shall provide to the Trustee, the Paying Agent and to all Holders at their respective addresses as shown on the Register, and to beneficial owners of the Securities where required by applicable law, a notice as provided in the Indenture. The Company will be required to purchase only Securities with respect to which a Holder has delivered a Purchase Notice in accordance with the terms and conditions of the Indenture and subject to the satisfaction of the other conditions set forth in the Indenture.

        7.    Conversion Rights.     (a) Subject to and upon compliance with the provisions of the Indenture and the occurrence of one or more of the conditions set forth in clause (d) of this paragraph 7, the Holder of Securities shall be entitled, at such Holder's option, at any time before the close of business on the Business Day immediately preceding July 15, 2024, to convert the Holder's Securities (or any portion of the principal amount hereof that is $1,000 or a multiple thereof), at the principal amount thereof or of such portion thereof into duly authorized, fully paid and nonassessable shares of Common Stock of the Company at the Conversion Rate in effect at the time of conversion.

        (b)   In the case of a Security (or a portion thereof) called for redemption, such conversion right in respect of the Security (or such portion thereof) so called shall expire at the close of business on the Business Day immediately preceding the Redemption Date, unless the Company defaults in making the payment due upon redemption. If a Holder exercises its Purchase Right or Put Purchase Right with respect to a Security (or a portion thereof), such conversion right in respect of the Security (or portion thereof) shall expire at the close of business on the Business Day preceding the Purchase Date or Put Purchase Date, as applicable.

        (c)   Each $1,000 principal amount of the Securities shall initially be convertible into 86.7905 shares of Common Stock (referred to as the "Conversion Rate"). The Conversion Price shall be initially equal to approximately $11.52 per share of Common Stock. The Conversion Rate shall be adjusted under certain circumstances as provided in the Indenture. If a Holder of Securities elects to convert its Securities in connection with a specified corporate transaction pursuant to Section 7(d)(iv)(B) below that occurs on or prior to July 15, 2009, and the corporate transaction also constitutes a transaction described in clause (2) of the definition of Change of Control, such Holder shall be entitled to receive, in addition to a number of shares of Common Stock equal to

A-7

the Conversion Rate per $1,000 principal amount of Securities, a number of Additional Shares as described in Section 12.01(a)(ii) of the Indenture.

        (d)   Regardless of anything else contained herein, Holders may surrender their Securities for conversion into shares of the Company's Common Stock prior to the close of business on the Business Day immediately preceding July 15, 2024 only in the following circumstances:

        (i)    Conversion Upon Satisfaction of Sale Price Condition.

        (A)  A Holder may surrender any of its Securities for conversion into shares of the Company's Common Stock in any fiscal quarter (and only during such fiscal quarter) after the fiscal quarter ending October 31, 2004 if the Sale Price of the Company's Common Stock, for at least 20 Trading Days during the period of 30 consecutive Trading Days ending on the last Trading Day of the previous fiscal quarter, is greater than or equal to 130% of the applicable Conversion Price per share of the Company's Common Stock on such last Trading Day.

        (B)  The "Sale Price" of the Company's Common Stock on any date means the closing sale price per share (or if no closing sale price is reported, the average of the bid and asked prices or, if more than one in either case, the average of the average bid and the average asked prices) on that date as reported in transactions for the principal U.S. securities exchange on which the Company's Common Stock is traded or, if the Company's Common Stock is not listed on a U.S. national or regional securities exchange, as reported by the Nasdaq National Market. The Sale Price shall be determined without reference to after-hours or extended market trading. If the Company's Common Stock is not listed for trading on a U.S. national or regional securities exchange and not reported by the Nasdaq National Market on the relevant date, the "Sale Price" shall be the last quoted bid price for the Company's Common Stock in the over-the-counter market on the relevant date as reported by the National Quotation Bureau or similar organization. If the Company's Common Stock is not so quoted, the "Sale Price" shall be the average of the mid-point of the last bid and asked prices for the Company's Common Stock on the relevant date from each of at least three nationally recognized independent investment banking firms selected by the Company for this purpose.

        (ii)    Conversion Upon Satisfaction of Trading Price Condition.

        (A)  A Holder may surrender its Securities for conversion into the Company's Common Stock during the five Business Days immediately following any five consecutive Trading-Day period (the "measurement period") in which the Trading Price per $1,000 principal amount of Securities (as determined following a request by a Holder of the Securities in accordance with the procedures described below) for each day of the measurement period was less than 98% of the product of the Sale Price of the Company's Common Stock and the then applicable Conversion Rate; provided, however, that a Holder may not convert Securities in reliance on this clause (d)(ii) of this paragraph 7 after July 15, 2019 if on any Trading Day during the measurement period, the Sale Price of the Company's Common Stock was between 100% and 130% of the Conversion Price in effect on such Trading Day.

        (B)  In connection with any conversion upon satisfaction of the condition set forth in clause (A) above, the Trustee shall have no obligation to determine the Trading Price of the Securities unless the Company has requested such determination, and the Company shall have no obligation to make such request unless the Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Securities would be less than 98% of the product of the Sale Price of the Company's

A-8

Common Stock and the then applicable Conversion Rate; at which time the Company shall instruct the Trustee to determine the Trading Price of the Securities beginning on the next Trading Day and on each successive Trading Day until the trading price is greater than or equal to 98% of the product of the Sale Price of the Company's Common Stock and the then applicable Conversion Rate.

        (iii)    Conversion Upon Notice of Redemption.    If the Company calls any or all of the Securities for redemption pursuant to the provisions of Article 10 of the Indenture, Holders may convert those Securities into the Company's Common Stock at any time prior to the close of business on the Business Day immediately preceding the Redemption Date, even if the Securities are not otherwise convertible at such time. If a Holder already has delivered a Put Purchase Notice with respect to a Security, however, the Holder may not surrender that Security for conversion until the Holder has withdrawn the Put Purchase Notice in accordance with the Indenture.

        (iv)    Conversion Upon Specified Corporate Transactions.

        (A)  If the Company elects to: (1) distribute to all holders of the Company's Common Stock rights entitling them to purchase shares of the Company's Common Stock at less than the Sale Price of a share of the Company's Common Stock on the Trading Day immediately preceding the declaration date of the distribution, or (2) distribute to all holders of the Company's Common Stock the Company's assets, debt securities or rights to purchase the Company's securities, which distribution has a per share value as determined by the Board of Directors exceeding 10% of the Sale Price of a share of the Company's Common Stock on the Trading Day immediately preceding the declaration date of the distribution, the Company must notify the Holders of the Securities at least 20 days prior to the ex-dividend date for such distribution. Upon such notice, Holders may surrender their Securities for conversion at any time until the earlier of the close of business on the Business Day immediately prior to the ex-dividend date or the Company's announcement that such distribution will not take place, even if the Securities are not otherwise convertible at such time. No Holder may exercise this right to convert if the Holder otherwise may participate in the distribution without conversion. The ex-dividend date is the first date upon which a sale of the Common Stock does not automatically transfer the right to receive the relevant distribution from the seller of the Common Stock to its buyer.

        (B)  If the Company is a party to a consolidation, merger or binding share exchange or any sale, lease or other transfer in one transaction or a series of related transactions of the consolidated assets of the Company and its Subsidiaries, substantially as an entirety, to any Person other than the Company or one or more of its Subsidiaries, pursuant to which the Company's Common Stock would be converted into cash, securities or property, a Holder may surrender Securities for conversion at any time from and after the date that is 15 days prior to the anticipated effective date of the transaction until 15 days after the actual effective date (the "Effective Date") of such transaction (or if such transaction also constitutes a Fundamental Change, the Purchase Date). The Company shall notify Holders and the Trustee as promptly as practicable following the date that it publicly announces any such transaction (but in no event less than 15 days prior to the Effective Date of such transaction).

        (e)   To exercise the conversion right, the Holder must surrender the Security (or portion thereof) duly endorsed or assigned to the Company or in blank, at the office of the Conversion Agent, accompanied by a duly signed conversion notice to the Company. Any Security surrendered for conversion during the period between the close of business on any Regular Record Date and

A-9

the opening of business on the corresponding Interest Payment Date shall be accompanied by payment of an amount equal to the accrued and unpaid interest (excluding Liquidated Damages, if any) payable on such Interest Payment Date by the Company on the principal amount of the Security being surrendered for conversion (but excluding any overdue interest on the principal amount of such Security so converted that exists at the time such Holder surrenders such Security for conversion). Notwithstanding the foregoing, any such Holder that surrenders for conversion any Security (a) that has been called for redemption by the Company in a notice of redemption given by the Company pursuant to Section 10.04 of the Indenture on a Redemption Date after such Regular Record Date and on or prior to the next succeeding Interest Payment Date or (b) with respect to which the Company has specified a Purchase Date that is after such Regular Record Date and on or prior to the next succeeding Interest Payment Date, in either case, need not pay the Company an amount equal to the interest on the principal amount of such Security so converted at the time such Holder surrenders such Security for conversion.

        (f)    No fractional shares of Common Stock shall be issued upon conversion of any Securities. Instead of any fractional share of Common Stock that would otherwise be issued upon conversion of such Securities, the Company shall pay a cash adjustment as provided in the Indenture.

        8.[Reserved]     

        9.    Denominations; Transfer; Exchange.     The Securities are issuable in registered form, without coupons, in denominations of $1,000 principal amount and whole multiples of $1,000 in excess thereof. A Holder may register the transfer or exchange of Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture.

        In the event of a redemption in part, neither the Company nor the Registrar shall be required to issue, register the transfer of, or exchange any certificated Securities during the period of 15 days immediately preceding the mailing of the redemption notice.

        In the event of redemption, conversion or purchase of the Securities in part only, a new Security or Securities for the unredeemed, unconverted or unpurchased portion thereof shall be issued in the name of the Holder hereof.

        10.    Persons Deemed Owners.     The registered Holder of this Security shall be treated as its owner for all purposes.

        11.    Unclaimed Money.     The Trustee and the Paying Agent shall pay to the Company any money held by them for the payment of principal or interest that remains unclaimed for two years after the date upon which such payment shall have become due. After payment to the Company, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of the Trustee and the Paying Agent with respect to such money shall cease.

        12.[Reserved]     

        13.    Amendment; Supplement; Waiver.     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Outstanding Securities (or such lesser amount as shall have acted at a meeting pursuant to the provisions of the Indenture). The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and

A-10

certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security or such other Security.

        No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest (including Liquidated Damages, if any) on this Security at the times, places and rate, and in the coin or currency, herein prescribed or to convert this Security as provided in the Indenture.

        14.    Defaults and Remedies.     The Indenture provides that an Event of Default with respect to the Securities occurs when any of the following occurs:

        (a)   the Company defaults in the payment of the principal on any of the Securities when it becomes due and payable, at Maturity, upon redemption or exercise of a Purchase Right or Put Purchase Right or otherwise; or

        (b)   the Company defaults in the payment of interest (including Liquidated Damages, if any) on any of the Securities when it becomes due and payable and such default continues for a period of 30 days; or

        (c)   the Company fails to deliver shares of Common Stock, together with cash instead of fractional shares, when those shares of Common Stock or cash instead of fractional shares is required to be delivered following conversion of a Security in accordance with the provisions of Article 12 of the Indenture and that failure continues for 10 days; or

        (d)   the Company fails to perform or observe any other term, covenant or agreement contained in the Securities or the Indenture and such default continues for a period of 60 days after written notice of such failure is given as specified in the Indenture; or

        (e)   (i) the Company fails to make any payment by the end of the applicable grace period, if any, after the maturity of any Indebtedness for borrowed money in an amount in excess of $25,000,000, or (ii) there is an acceleration of any Indebtedness for borrowed money in an amount in excess of $25,000,000 because of a default with respect to such Indebtedness without such Indebtedness having been discharged or such acceleration having been cured, waived, rescinded or annulled, in the case of either clause (i) or (ii) above, for a period of 30 days after written notice is given to the Company as specified in the Indenture; or

        (f)    the Company fails, within 15 days after the occurrence of a Fundamental Change, to give to each Holder of Securities notice pursuant to Section 11.01(b) of the Indenture; or

        (g)   there are certain events of bankruptcy, insolvency or reorganization of the Company or any Significant Subsidiary of the Company.

        If an Event of Default shall occur and be continuing, the principal of all the Securities maybe declared due and payable in the manner and with the effect provided in the Indenture.

        15.    Authentication.     This Security shall not be valid until the Trustee (or authenticating agent) executes the certificate of authentication on the other side of this Security.

        16.    Abbreviations.     Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian) and U/G/M/A (= Uniform Gifts to Minors Act).

A-11

        17.    Additional Rights of Holders of Registrable Securities.     In addition to the rights provided to Holders under the Indenture, Holders of Registrable Securities shall have all the rights set forth in the Registration Rights Agreement.

        18.    CUSIP Numbers.     Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on this Security and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on this Security or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

        19.    Governing Law.     The Indenture and this Security shall be governed by, and construed in accordance with, the laws of the State of New York.

        20.    Successor Corporation.     In the event a successor corporation assumes all the obligations of the Company under this Security, pursuant to the terms hereof and of the Indenture, the Company shall be released from all such obligations.
